The funeral was held at Church on the Hill in Kamagugu, outside Mbombela, not far from the house Godrich bought for Gardee, 28, and her brother, Noble.
Gardee's body was found in a field outside Mbombela on Tuesday, four days after she disappeared. She had been murdered. A 39-year-old man who was arrested on Friday in connection with the murder is due to appear in the Nelspruit magistrate's court on Monday.
Welcoming guests to the funeral, a family member said less than four years ago they gathered at the same venue for the funeral of Hillary's mother, Nnenna Chinyere née Amonyeze.
